( Figs. 7 , 19 , 37, 38, 64, 65, 96, 114, 115, 133, 144, 162, 163, 181) Type material. Holotype : CHINA : Zhejiang Prov.: 3, West Tianmushan Mt. ( 30°18’31”N 119°29’01”E ), elev. 300 m , Jia-Yao Hu & Liang Tang leg., 17.v.2006 . Paratypes : CHINA : Zhejiang Prov.: 13, 4ƤƤ, same data as holotype (all SHNUC ). Description. Body ( Fig. 7 ) yellow (probably because the specimen is teneral); maxillary palpi and tarsi lighter in color; body length 2.92–2.96 mm, combined width of elytra 1.27–1.29 mm. Head as long as wide, frontal margin anterior to eyes gradually narrowed toward apex. Antenna ( Fig. 96 ) with each antennomere elongate, scape three times as long as pedicel and three times as long as wide, pedicel short, antennomere III longer than scape, III–V and VII subequal in length, VI slightly longer than VII, VIII short, about as long as pedicel, IX–XI each enlarged and oval, forming an unmodified club, IX slightly longer than X, XI the widest. Maxillary palpus ( Fig. 144 ) with palpomere II pedunculate, nearly straight at basal half, II–IV each protuberant on lateral sides. Mandibles ( Fig. 133 ) each with three large teeth and one to two smaller teeth on mesal margin. Pronotum longer than wide, coarsely punctured and densely pubescent. Elytra ( Fig. 19 ) covered by short pubescence, each elytron with longitudinal sulcus reaching apical three-fourths of elytral length. Legs (Figs. 64, 65) with protrochanters and profemora each with a spine, mesotrochanters each with a large and a smaller apical spine, hind legs not armed with spines. Abdomen (Figs. 37, 38) with tergite IV about twice as long as next, with a pair of discal carinae reaching apical one-fourth, tergite VIII (Fig. 115) and sternite VIII (Fig. 114) most similar to those of P . cornutus , but apical margin of tergite VIII straighter. Aedeagus ( Figs. 162, 163 ) very weakly sclerotized (probably because the specimen is teneral), with apex of median lobe acute; endophallus ( Fig. 181 ) with asymmetrical U-shaped sclerite, both branches narrowed from base toward apex; parameres paired, oriented apicad, each with short seta on mediolateral side. Female. Smaller, antennal club unmodified, basal metaventral process absent. Remarks. This species can be recognized by the shape of the apical part (see description) of the median lobe ( Figs. 162, 163 ) and the basal margin of the basal bulb that is slightly pointed. Distribution. China (Zhejiang Province). Etymology. The species name is an adjective and refers to the name of the type locality.
